Signed-off-by: Roja Rani Yarubandi --- Changes in V3: - Broken the huge V2 patch into 3 smaller patches. 1. QSPI DT nodes 2. QUP wrapper_0 DT nodes 3. QUP wrapper_1 DT nodes Changes in V2: - As per Doug's comments removed pinmux/pinconf subnodes. - As per Doug's comments split of SPI, UART nodes has been done. - Moved QSPI node before aps_smmu as per the order. arch/arm64/boot/dts/qcom/sc7280-idp.dts | 29 ++++++++++++ arch/arm64/boot/dts/qcom/sc7280.dtsi | 61 +++++++++++++++++++++++++ 2 files changed, 90 insertions(+) diff --git a/arch/arm64/boot/dts/qcom/sc7280-idp.dts b/arch/arm64/boot/dts/qcom/sc7280-idp.dts index 3900cfc09562..d0edffc15736 100644 --- a/arch/arm64/boot/dts/qcom/sc7280-idp.dts +++ b/arch/arm64/boot/dts/qcom/sc7280-idp.dts @@ -268,6 +268,22 @@ pmr735b_die_temp { }; }; +&qspi { + status = "okay"; + pinctrl-names = "default"; + pinctrl-0 = <&qspi_clk>, <&qspi_cs0>, <&qspi_data01>; + + flash@0 { + compatible = "jedec,spi-nor"; + reg = <0>; + + /* TODO: Increase frequency after testing */ + spi-max-frequency = <25000000>; + spi-tx-bus-width = <2>; + spi-rx-bus-width = <2>; + }; +}; + &qupv3_id_0 { status = "okay"; }; @@ -278,6 +294,19 @@ &uart5 { /* PINCTRL - additions to nodes defined in sc7280.dtsi */ +&qspi_cs0 { + bias-disable; +}; + +&qspi_clk { + bias-disable; +}; + +&qspi_data01 { + /* High-Z when no transfers; nice to park the lines */ + bias-pull-up; +}; + &qup_uart5_default { tx { pins = "gpio46"; diff --git a/arch/arm64/boot/dts/qcom/sc7280.dtsi b/arch/arm64/boot/dts/qcom/sc7280.dtsi index 6c9d5eb93f93..3047ab802cd2 100644 --- a/arch/arm64/boot/dts/qcom/sc7280.dtsi +++ b/arch/arm64/boot/dts/qcom/sc7280.dtsi @@ -1061,6 +1061,42 @@ apss_merge_funnel_in: endpoint { }; }; + qspi_opp_table: qspi-opp-table { + compatible = "operating-points-v2"; + + opp-75000000 { + opp-hz = /bits/ 64 <75000000>; + required-opps = <&rpmhpd_opp_low_svs>; + }; + + opp-150000000 { + opp-hz = /bits/ 64 <150000000>; + required-opps = <&rpmhpd_opp_svs>; + }; + + opp-300000000 { + opp-hz = /bits/ 64 <300000000>; + required-opps = <&rpmhpd_opp_nom>; + }; + }; + + qspi: spi@88dc000 { + compatible = "qcom,qspi-v1"; + reg = <0 0x088dc000 0 0x1000>; + #address-cells = <1>; + #size-cells = <0>; + interrupts = ; + clocks = <&gcc GCC_QSPI_CNOC_PERIPH_AHB_CLK>, + <&gcc GCC_QSPI_CORE_CLK>; + clock-names = "iface", "core"; + interconnects = <&gem_noc MASTER_APPSS_PROC 0 + &cnoc2 SLAVE_QSPI_0 0>; + interconnect-names = "qspi-config"; + power-domains = <&rpmhpd SC7280_CX>; + operating-points-v2 = <&qspi_opp_table>; + status = "disabled"; + }; + system-cache-controller@9200000 { compatible = "qcom,sc7280-llcc"; reg = <0 0x09200000 0 0xd0000>, <0 0x09600000 0 0x50000>; @@ -1186,6 +1222,31 @@ tlmm: pinctrl@f100000 { gpio-ranges = <&tlmm 0 0 175>; wakeup-parent = <&pdc>; + qspi_clk: qspi-clk { + pins = "gpio14"; + function = "qspi_clk"; + }; + + qspi_cs0: qspi-cs0 { + pins = "gpio15"; + function = "qspi_cs"; + }; + + qspi_cs1: qspi-cs1 { + pins = "gpio19"; + function = "qspi_cs"; + }; + + qspi_data01: qspi-data01 { + pins = "gpio12", "gpio13"; + function = "qspi_data"; + }; + + qspi_data12: qspi-data12 { + pins = "gpio16", "gpio17"; + function = "qspi_data"; + }; + qup_uart5_default: qup-uart5-default { pins = "gpio46", "gpio47"; function = "qup13";
